I think that the main issue is the screw that sits inside the helical focuser is smaller in diameter than the worm channel thread in which it rotates. As well, there is a small gap in between the focuser and the sliding 1/ 1/4 barrel tube.

Have just emailed Lumicon for a response.

Is this meant to be good enough for a $400 80mm short focus refractor/finder? Can it be repaired or an alternative focuser sourced for an 80mm ID barrel?

Look forward to comments.
